Abstract
One of the challenges of antenna design for microwave-based breast screening systems is to minimize the surface waves propagating at the interface between the substrate and the biological tissue. The surface waves become additionally pronounced inside the substrate with a confining ground plane, which is required for unidirectionality and blocks environmental radiation. This paper introduces a simplified human breast model and presents a quantitative analysis of the existing surface waves. Then, we propose an array of 16 cavity-backed patch antennas with parasitic elements, designed to operate in the 3.1-5.1 GHz range. Each antenna element is optimized to function next to the breast tissue. Full-wave simulations reveal that the proposed antenna array achieves higher unidirectionality and suppressed mutual coupling levels. In addition, the design offers improved bio-compatibility when compared with the previous designs, as it employs the SYLGARD™ 184 silicone elastomer PDMS substrate.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from it
